Problems solved by technology
[0004] However, due to the long generation time of HOG features and SIFT features, and the large amount of calculation of SVM model or kNN nearest neighbor model, the recognition of body color takes a long time and the real-time performance is poor.

The invention discloses a vehicle body color recognition method, system and device and a computer readable storage medium. The vehicle body color recognition method intercepts a picture of a vehicle body color effective feature region from a vehicle body color picture according to license plate position information, takes the picture as a to-be-identified picture and inputting the to-be-identifiedpicture into a trained vehicle body color identification model based on a CNN network structure, enables the vehicle body color recognition model to extract features in the to-be-recognized picture and predict the vehicle body color category, outputs the prediction result of the vehicle body color category, and achieves automatic extraction of vehicle body color picture features and prediction ofthe vehicle body color category, wherein the size of the to-be-recognized picture obtained through interception is small, and interference information is little, and the data size is small, and the speed and precision of vehicle body color recognition are improved.
Description
technical field [0001] The present invention relates to the technical field of machine vision recognition, in particular to a vehicle body color recognition method, system, device and computer readable medium. Background technique [0002] With the improvement of machine vision recognition technology, body color recognition technology continues to improve. [0003] Body color is a key feature of vehicles. In places such as traffic buckles and parking lot entrances and exits, the recognition of body color can provide an important auxiliary function for the confirmation of vehicle information. Existing technologies are usually based on artificially designed Histogram of Oriented Gradient (HOG, Histogram of Oriented Gradient) features or scale-invariant feature transform (SIFT, Scale-invariant feature transform) features, using Support Vector Machine (SVM, Support VectorMachine) models or The k-nearest neighbor (kNN, k-Nearest Neighbor) model is used to complete the recognitio...
